M5lp 0210 03 Ported Modular Heads Modular Cylinder Heads

The Computer Numerical Control machine is the first stop for our modular cylinder heads. Cory Roth, a well-known heads-up racer, handles this step of the process. The CNC cuts are actually memorized from hand-ported versions worked up at Fox Lake. It takes about 7.5 hours per pair to complete the cutting.
